In this episode of The Diary of a CEO, featuring Steven Bartlett and Dr. Victoria Sampson, Dr Sampson: Your Oral Microbiome Is Linked To This Disease! explores saliva, Sex, And Disease: How Oral Microbes Quietly Control Your Health Dr. Victoria Sampson explains how the oral microbiome—700 species and billions of bacteria—acts as a gateway to the rest of the body, influencing everything from heart disease and Alzheimer’s to fertility and erectile dysfunction.
Saliva, Sex, And Disease: How Oral Microbes Quietly Control Your Health
Dr. Victoria Sampson explains how the oral microbiome—700 species and billions of bacteria—acts as a gateway to the rest of the body, influencing everything from heart disease and Alzheimer’s to fertility and erectile dysfunction.
She outlines three main mechanisms of harm: chronic low‑grade inflammation, direct bacterial spread from the mouth to organs, and toxins that damage blood vessels and brain tissue.
New research links poor oral health to severe COVID, rheumatoid arthritis, colorectal and breast cancer, pregnancy complications, and ADHD‑like symptoms via mouth breathing.
Throughout, she shares practical protocols: how and when to brush, what to eat and avoid, the role of green tea, sugar‑free gum, probiotics, and why saliva testing may become as routine as blood tests.

Is there a link between our oral health and our fertility?
Yes. This is some of the newest research that's coming out. They found that over 90% of men who wasn't able to conceive with their partners had a oral disease. For those who got treated, there was a 70% improvement in pregnancy. Now, research has also found that if a woman has gum disease, it takes them two months longer to conceive. And I'm the only one who's talking about it.
And who are you?
I am the Saliva Queen. Dr. Victoria Sampson is the trailblazing dentist...
Whose data-driven research has uncovered the shocking link between our mouths...
And some of the world's most destructive conditions. More than 90% of diseases can be traced back to our microbiomes, and we now understand that having an imbalanced oral microbiome increases your risk of high blood pressure, heart disease, Alzheimer's, rheumatoid arthritis. And even men who have gum disease are 2.85 times more likely to have erectile dysfunction.
Really?
Yeah. And then another study also showed there's oral bacteria that can make cancer more aggressive and harder to treat as well.
But what is it that causes all of this?
Poor oral hygiene, sugar, stress, but also some of us genetically will have mutations which can cause disease. But there's ways to fix it. For example, I had a patient who had terrible arthritis and terrible gum disease, and when I treated the gum disease, her rheumatoid arthritis got better, to the point where she was actually able to walk again.
Wow.
Yeah.
So let's talk about what we can do about it. Is there any time where I shouldn't brush my teeth? Do I spit or rinse after I brush my teeth? Chewing gum, coffee, mouthwash, good or bad for me?
Let's go through all of that. So weirdly...

Um, my mission is to show people that the mouth is the gateway to the rest of the body. And if they really want to achieve full body health, it starts with the mouth first.
